Subject Optimistic mode with serializable vs read_committed
Date Tue, 03 Jul 2018 19:10:36 GMT

I was reading this documentation,
to understand the difference between Optimistic mode with Serializable vs
read_committed. The only difference I see from the explanation given is
that for Serializable isolation, the "*primary nodes manage the transaction
requests internally*" before an ACK is sent to the coordinator while for
read_committed, the ACK is sent immediately and the nodes "*manage the
transaction requests internally*" later.

My question:

   1. What does "*primary nodes manage the transaction requests
internally"* exactly
   2. What are the specific things a node has to do to manage transaction
   requests internally?
